Psalm 21

The king's thanksgiving after the victory prayed for in Psalm 20: his heart's desire granted and joy in God's presence. Its stability comes from God's chesed, not the king's strength. The second half is fierce judgment on God's enemies, and I won't soften it; it assumes God's justice is real and final.

"For the king trusts in the LORD; through the loving devotion of the Most High, he will not be shaken." (Psalm 21:7)
